Answer:
If the whole transaction is written separately from the beginning, an algebraic equation is obtained
Step-by-step explanation:
![4x = s](https://tex.z-dn.net/?f=4x%20%3D%20s)
![- 2x = w](https://tex.z-dn.net/?f=%20-%202x%20%3D%20w)
![w \times s = - 8 {x}^{2}](https://tex.z-dn.net/?f=w%20%5Ctimes%20s%20%3D%20%20-%208%20%7Bx%7D%5E%7B2%7D%20)
![w = s = s \times s = 16 {x}^{2}](https://tex.z-dn.net/?f=w%20%3D%20s%20%3D%20s%20%5Ctimes%20s%20%3D%2016%20%7Bx%7D%5E%7B2%7D%20)
![- 8 {x}^{2} + 16 {x}^{2} = 8 {x}^{2}](https://tex.z-dn.net/?f=%20-%208%20%7Bx%7D%5E%7B2%7D%20%20%2B%2016%20%7Bx%7D%5E%7B2%7D%20%20%3D%208%20%7Bx%7D%5E%7B2%7D%20)
This is the way to get the answer
Answer:
he ended up walking only 18 meters north after all
![y = 40000{(1.04)}^{x}](https://tex.z-dn.net/?f=y%20%20%3D%2040000%7B%281.04%29%7D%5E%7Bx%7D%20)
After 11 years, her salary will be $61,578.16
Step-by-step explanation:
![x = 11\\ y = 40000 {(1.04})^{11} \\ y = 61,578.162...](https://tex.z-dn.net/?f=%20x%20%3D%2011%5C%5C%20y%20%3D%2040000%20%7B%281.04%7D%29%5E%7B11%7D%20%20%5C%5C%20y%20%3D%2061%2C578.162...)
